Extremely Slow Clang Autocomplete suggestions [VGDB ROS LINUX PCL]

[NZNobody]

Hello,

Could you please advise me how to determine why my clang auto complete engine is constantly reparsing 1000’s of files and making autocomplete nearly unusable. I have asked a similar question before, but was unable to get a solution. To describe the scenario:

Visual Studio 2015, VGDB 5.2 Windows 7, Workstation Laptop (i7-5600, 16GB RAM, 500GB SSD)

Working in a solution with 9-10 projects, but usually only load 1 or 2 (to attempt to help VGDB). All 10 projects contain roughly max 100 source files, and each are relatively small (I am writing nodes for ROS).

Because I am deploying to a remote Linux ARM machine with Robot Operating System (ROS) and Point Cloud Library (PCL) my includes are somewhat larger. Roughly 20,000 files totaling ~200 MB. However of that 90% are standard Linux includes. 1k Files are PCL and about 1k are ROS. 10k are Boost libraries. All the includes are cached locally.

Working on a single project with a single header ( < 80 lines of code) and a single source file (~300 lines) has me waiting 30 seconds often for auto complete. This is ridiculous and I must have configured something wrong.

If you can tell me what I would need to provide for you to analyse this that would be great. Or if anyone else here works with ROS?
<h2>Solutions Tried:</h2>

• Unloading / reloading projects, entire solution.
• Deleting the .db file from the solution to force a re-scan encase of error. Delete cache folders as well.
• Enabled Find missing headers, and locate all missing headers.
• Crying.

None of these have helped 🙁

Hi,

Thanks a lot for the log file. Normally VisualGDB optimizes the IntelliSense by pre-compiling a “preamble” – the part of the source file that only contains #include<> statements.

Looks like you are doing the following:

1. Editing the main source file
2. Switching to a header file that is a part of the preamble
3. Editing the header file
4. Switching back to the source file

This causes a full reparse of the main source file that is a very slow operation.

If you need to do that often, please try rearranging the #include<> statements in your main file as follows:

#include <rarely modified files>
static const int unused = 0; //or any other valid C/C++ statement
#include <frequently modified files>

This should force VisualGDB to not treat the frequently modified files as a part of the preamble.

You can double-check what is being reparsed in the Clang IntelliSense Diagnostics Console:

[+1:32:49.913] Found an outdated PSF 0 due to c:\users\manu.lange\source\ros_projects\rex_interface\include\rex_interface\rex_interface.hpp during initial check. It will be re-built.
[+1:32:49.928] Rebuilding PSF 0 (normal preamble)...

PSF 0 (normal preamble) refers to the preamble described above (combination of the #include<> statements from the top of the file). Normally VisualGDB should say that PSF (precompiled source fragment) 0 is up-to-date.

If this helps, please let us know and we will consider adding a mechanism for auto-detecting this and handling it automatically.

Hello,

Thanks for your suggestions. I have tested them with the following results:

Inserting the ‘IntelliSense Interupt’ c++ line as suggested does indeed reduce the rebuild time, by changing type.

PRIOR to inserting the line:

[+0:18:41.877] Rebuilding PSF 0 (normal preamble)...

[+0:19:19.786] Operation completed: Parse - Check [38164 msec]

 

POST inserting the line:

[+0:15:34.040] Found an outdated PSF 1 due to c:\users\manu.lange\source\ros_projects\rex_interface\include\rex_interface\rex_interface.hpp during initial check. It will be re-built.

[+0:15:44.604] Operation completed: Parse - Check [10827 msec]

 

However, there still remains a few key issues.

1. The 10-11 second update is still performed every time that I save the document. I’m guessing this is unavoidable, even if no contect of the document has changed. It is the case often that I press CTRL-S a lot, just out of habbit. This is quickly a very frustrating habbit with no autocomplete for the next 10-11 seconds.
2. The update length for just changed the .cpp file (obviously increased). Without the interrupting line, it was only 9.5s, with it was 10.5 (Checked multiple times).
3. I still get a 30+ second rebuild if I save the .cpp file and switch to the header. This is a little odd, since ‘technically’ the header doesn’t know of the source. It appears to default to: [+0:22:28.903] Rebuilding PSF 0 (normal preamble)…

Hi,

Sorry, looks like you are using v5.1. Please try the latest v5.2 beta. It uses separate internal environments to handle the long reparse and critical operations like code completion, so it should be much faster.

[NZNobody]

Hello,

I checked versions, as in first post I was on 5.2 (Preview 1). I noted that there was a preview 3 and installed that, but the same actions produce the same results sadly. LOG FILE.

Saving (with no changes) the .cpp causes a 30s rebuild when switching to the .hpp

Thanks 🙂

Hi,

Thanks for the log. It looks like you have modified the main source file and then tried reparsing one of the header files. This does look like a bottleneck and we could optimize this further.

Can you confirm that code completion within the main .cpp file works reasonably fast after the trick with explicitly ending the preamble?

[NZNobody]

I can confirm that explicitly ending the preamble reduced re-parsing times for the .cpp file from roughly 38s to 11s.

Maybe there is a similar trick for the .hpp file, but since in the .hpp I don’t explicitly ‘include’ the .cpp file I don’t know how to separate these. You are right, technically I modified the .cpp file by re-saving it. Then simply switching back to the .hpp causes a re-parse. In my normal programming behavior I am often saving my source files and then briefly wanting to look at a header for information, so then having to wait 30+s to carry on is inconvenient.

Regards,

Hi,

Unfortunately currently there is no such trick for the .hpp file, but we will look into handling this automatically once the final v5.2 is out (beginning of the next week). Right now VisualGDB simply checks for the timestamp of the main .cpp file, but we could easily make it check the relevant file contents.

One major optimization of v5.2 is that code completion (when you type code or press ctrl-space) should work even while the 10-second ‘parse – check’ phase is active, so the 10-second delay should only affect advanced colorization of newly typed text, but not most of the normal functionality. Could you confirm that it actually works for your project?

[NZNobody]

Hello,

 

I can confirm that if I trigger a reparse by say saving the current file, I CAN still access code-completion during that time.

If I however trigger a full rebuild (by say saving the .cpp, and switching to .hpp, or without the preamble guard), then I CANNOT access code completion during rebuild. View below excerpt for example:
